[. . . ] KN8 SLI AMD Athlon 64/64FX/64x2 Dual Core System Board Socket 939 User's Manual 4200-0466-01 Rev. 1. 00 Copyright and Warranty Notice The information in this document is subject to change without notice and does not represent a commitment on part of the vendor, who assumes no liability or responsibility for any errors that may appear in this manual. No warranty or representation, either expressed or implied, is made with respect to the quality, accuracy or fitness for any particular part of this document. In no event shall the manufacturer be liable for direct, indirect, special, incidental or consequential damages arising from any defect or error in this manual or product. [. . . ] Write Recovery Time: This item specifies the time measured from the last write datum is safely registered by the DRAM. Write to Read Delay: This item specifies the time measured from the rising edge following the last non-masked data strobe to the rising edge of the next read command. DRAM Command Rate: When the host (northbridge) locates the desired memory address, it then processes the wait state of commands. Async Latency value: Bank Interleaving: 3-11 This item specifies the Max Async value. Depending on your SDRAM module structure, the 4-Way setting can offer the best performance. If you choose the wrong setting, the computer system will not run in a stable manner. For detailed information on your SDRAM module, please ask your SDRAM module manufacturer. Burst Length DDR SDRAM modules provide a Burst mode that means an auto precharge function for programmable READ or WRITE burst lengths of 2, 4 or 8 locations. This means that if we set burst length to 8, the address bus will access 8 bytes each cycle to precharge, etc. DRAM Drive Strength: Force 64-bit mode always: R/W Queue Bypass Counter: Bypass Max: Idle Cycle Limit(ILD-Lmt): Dynamic Idle Cycle Count: This item specifies the mode of DRAM Drive Strength. The MTRR (Memory-Type and Range Registers) controls the access and cacheability of memory regions in the processor. 32 bit Dram Memory Hole: This item selects the method to remap the 32 bit Dram memory hole. Leave this item to its default "Auto" Setting. # Back to Advanced Chipset Features Setup Menu: SSE/SSE2 Instructions: This item allows you to Enable or Disable the SSE/SSE2 (Streaming SIMD Extensions) instruction set. System BIOS Cacheable: Two options are available: Disabled or Enabled. When you select Enabled, you get faster system BIOS executing speed via the L2 cache.
